This invention relates to improvements in shoes and more particularly toa shoe having a resilient longitudinal arch sup ort secured to the uppersurface of the inso e adja- 5 cent the inner margin of the shoe. Thepresent invention is an improvement in the construction shown in mycoendin application, Serial No. 426,559, filed Fe ruary 7, 1930.

1o The object of the invention is to provide a shoe with a longitudinalarch support made of resilient material such as sponge rubber orneumatically inflated rubber.

nother object is to so construct the arch ort that it will eflicientlysupport the hig est part of the arch of the foot, that is, the partadjacent the inner margin of the foot; and that it will not spreadoutwardly or alter the general contour of its bea-ring surface whenpressure is applied to the arc support.

In the drawings Fig. 1 is a top lan view of an insole and leathercovering t erefor, having secured to the top of the insole an archsupport embodyln my invention, the leather cover begvbro en away to showthe arch support.

sup

is a transverse vertical section of a shoe embodying my invention, thesame be ing taken on the glane indicated by the dotted lines 2 2 of ig.1.

Fig. 3 is a view similar to Fig. 2, showing a modified form of arch suport.

Fig. 4 is a side elevation o an insole and arch support embodying myinvention, as the same appear when looking toward the inner side margin.

In that embodiment of my invention shown in the drawin 10 indicates aconventional outer sole osa shoe, 11 the leather uppers, 12 the liningfor the uppers, 13 a conventional inner sole, 14 the welt, and 15 aleather covering for the insole. These lpgrts are secured together in amanner well own in shoe construction.

Between the inner sole 13 and outer sole 10, extending longitudinally ofthe shoe adjacent the margin at the outer side of the shoe is asubstantially rifid arch support, preferably in the form o a metalplate' 16 secured to the under side of the insole 13. The space betweenthe inner and outer soles not occupied b the rigid arch support 16 isfilled with ii ling material 17.

Adjacent the inner margin of the insole, and extending longitudinally ofthe shoe, and under the arch of the foot, lis a resilient arch support18 preferably made of sponge rubber. It is cemented to the inner sole 13and is highest directly under the arch of l 559, filed February 7, 1930.

One of the novel features of improvement upon the structure shown insaid application consists of a side support for the flexible arch whichwill now be described.

A relatively thin, stiff piece of material 20 having a substantiallstraight lower margin for contacting withI the top surface of the edge21 of the insole, and having a curved upper margin 22 taperingdownwardly at each end toward the lower margin, is cemented to the sideof the arch support 18. The outer side 23 of the arch support 18 and therelatively stiff side support 20 are con-v cave longitudinally and areinclined downwardly and inwardly from their top margins toward theirline of connection to the lnsole adjacent the inner margins of the shoe.

After the side support has been cemented to the resilient arch support,the latter is cemented to the upper surface of the insole and thereafterthe leather covering 15 may be placed over the arch and insole. Withoutthe side member 20 for supporting the overhanging, inclined side surface23 of the arch support 18, said arch support would be apt to yieldunduly under pressure and would be forced downwardly and outwardly tosuch an extent that considerable of its supporting qualit for thehighest part of the arch ofthe floot might be lost. With `2 l nemen theside support 20 rst secured to the resilient arch 1 .in the mannershown, the high' est portion of the arch of the foot is well sunplportedand the tenden to displace the ient material toward e outer of the innerside of the shoe is avoided. construction holds the top surface of thearch support as intended, with its highest portion adjacent the marginand ually 1 slo ing toward the toe, heel and si e.

lthough the addition of a side saulpport 20 is a detail of construction,it is a v uable improvement in the reparation of a shoe having aresilient arc secured to the inside of the shoe above the insole. v

In Fig. 3, a modified form of resilient arch has been shown. Itcomprises a flexible casin 24 preferabl made of rubber neumatica lyinflated. ts shape is simi ar to the arch support 18 made of spongerubber and it is also provided with a relatively stiff side support 20such as described in connection with Figs. 1 and 2.

Obviously, changes 'in details of construc- 25'tion may be made withoutde arting from the scope of my invention, an I do not intend to belimited to the precise' form shown and described, except as pointed outin the ap ended claims. 3 clamz Y 1. In a shoe comprising an insole,outer sole and uppers secured to ther, a resilient arch support securedto t e upper surface of the insole, extending longitudinally of i thesole under the arch of the foot adjacent the mar of the inner side ofthe shoe, the outer si e surface of said arch support being concavelongitudinally and incllned downwardly from its top margin toward thein- 40 sole, a side member made of relativelysti material, shapedcomplemental to the side surface of said support and cemented to saidsupport, and a leather cover extendin over the top and sides of theinsole, the arc supl port and side support for the arch.

2. A shoe comprising an outer sole, an inner sole, leather u pers, anarch support made of sponge rub r located on the inner sole adjacent itsouter margin along the inner longitudinal side of the inner sole, arelatively stiff upright member secured to the vspon e rubber supportalong its concave outer si e surface, and a cover extending over the topof the inner sole and arch su port and downwardly adjacent the relativey stiff member, between the inner sole and the 4 uppers of the shoe.
